  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description of the first embodiment, left and right indicate the left and right directions in FIG. As shown in FIGS. 1, 2, and 3 (a) to 3 (c), the first embodiment of the ventilation structure includes a ventilation device 1 and an ion generator 2, and includes a building opening. It is installed with the window 100 in the part. More specifically, it is provided adjacent to the side of the window 100 and is sandwiched between the stand 101 and the casing 102. On the left and right sides, there are two frame members 5a and 5b extending vertically, and the vertical lengths of the frame members 5a and 5b are the same as the height of the window 100. It is fixed. And the wall surface part 6 is provided in the outdoor side end between the two frame materials 5a and 5b, and the space opened indoors is formed. Furthermore, an invisible eye 7 is provided at a position of about ３ from the upper end between the two frame members 5a and 5b, and the space between the frame members 5a and 5b is partitioned vertically. The ventilation device 1 is provided on the lower side, and the ion generator 2 is provided on the upper side.

  The ventilator 1 is a so-called constant air volume natural ventilator, and has a door 11 on the indoor side as shown in FIGS. 1, 2, and 3 (c). The door 11 opens to the indoor side with the right end as a suspension, and is rotatably attached to the right frame member 5b. A handle 12 for opening the door 11 is provided on the indoor side surface of the door 11. In addition, a number of slits 61 extending in the left-right direction are provided on the lower side of the wall surface 6 on the outside of the wall 7 so that the interior and the exterior communicate with each other when the door 11 is opened. Furthermore, a blade-shaped adjusting plate 13 is provided between the two frame members 5a and 5b. The adjustment plate 13 is rotatably provided on the left frame member 5a with the left end as the rotation center.

In addition, internal walls 14 a and 14 b provided on the left and right frame members 5 a and 5 b are located on the indoor side of the adjustment plate 13, and a ventilation path 15 is formed between both the internal walls 14 a and 14 b. As the adjusting plate 13 rotates inward (clockwise), the air passage 15 is blocked and narrowed. Further, a screen door 16 is provided in the air passage 15. According to the ventilation device 1 configured in this way, ventilation can be performed arbitrarily by opening the door 11. At that time, when the wind is weak and the wind pressure is less than the urging force of the spring member, the adjusting plate 13 does not move and the air passage 15 is in the widest state. When the wind becomes strong and the wind pressure exceeds the urging force of the spring member, the adjustment plate 13 rotates against the urging force to the indoor side, and the air passage 15 is blocked and narrowed. Therefore, since the ventilation path 15 becomes narrower as the wind becomes stronger, as a result, the ventilation amount becomes a constant amount regardless of the strength of the wind, and a constant air volume natural ventilation becomes possible.

According to the ion generator 2 configured as described above, by driving the fan 22, indoor air is taken in from the lower intake port 21, passed through the deodorizing filter 27, and ions are adsorbed to the air, It blows out from the upper blower outlet 23 (flow shown by the arrow in FIG. 4). A slit-like cover 28 is attached to the indoor side surface of the ion generator 2, and the intake 21 portion of the cover 28 is separate and detachable so that the deodorizing filter 27 can be replaced. It has become. Furthermore, a cover 29 is also attached to the indoor side surfaces of the power supply device 25 and the switch 26, and the design of the cover 28 of the ion generator 2 is unified.

  According to the first embodiment of the ventilation structure configured as described above, since the ventilator 1 is a constant air volume natural ventilator, it is possible to reduce the momentum of the wind during a strong wind without using a machine, and the situation of the outdoor wind Regardless of this, a certain amount of natural wind can be taken into the room and discharged. And air pollutants, dust, smells and other invisible unpleasant causative substances that enter the room due to ventilation are taken into the ion generator 2 and adsorbed with ions to suppress their action, thereby improving the air quality. Can be improved. In addition, ions can be diffused over a wide area in the room by being put on the air flow taken in by the ventilator 1, and the action of pollen and the like drifting in the room can be suppressed. Furthermore, since the deodorizing filter 27 is provided in the intake port 21 of the ion generator 2, the odor of air can be suppressed thereby. Moreover, since the ion generator 2 is provided in the upper part of the ventilator 1, the produced | generated ion can pour down on the air which flows in from the ventilator 1 from upper direction, and it can suppress pollen etc. efficiently, and ion is the ventilator 1. It spreads over a wide area on the flow of air flowing in. Furthermore, since the quality of air is improved by the ion generator 2, it is not necessary to provide a filter in the ventilation device 1, and the problem that the ventilation rate is reduced by the filter does not occur. Moreover, since the ion generator 2 has the fan 22, even when it is not ventilating, the quality of air can be improved by taking in indoor air with the fan 22, adsorb | sucking and blowing out ion. Furthermore, since it is not necessary to place the ion generator 2 on a floor or a shelf, it does not take up space. Moreover, since the ion generator 2 is located on the upper side of the ventilator 1 and the intake port 21 is located at the lower part of the ion generator device 2, the intake port 21 is close to the ventilator 1. As a result, the air flowing from the outside is taken in immediately, so that pollen, dust, smell, etc. are not spread as much as possible inside the room. And since the blower outlet 23 is provided in the position higher than the inlet 21, ion can be diffused more widely indoors. Moreover, since the inlet 21 is provided in the lower side in the ion generator 2, it is easy to reach and maintenance, such as replacement | exchange of the deodorizing filter 27, is easy.

Demonstrate. For example, as shown in FIG. 5, ventilation structures are provided at the four corners of the living space, air is supplied from the two ventilation structures on the leeward side, and exhausted from the two ventilation structures on the leeward side. An air flow from the upper side toward the leeward side is formed. And since ion diffuses on the whole living space on this air flow, pollen, dust, smell, etc. can be controlled more effectively. Depending on the wind direction, which ventilation structure supplies air and which ventilation structure exhausts varies as appropriate, but some predetermined air flows are formed in the room. When installing a movable air purifier, etc., it may not function effectively in relation to the air flow in the room, but if a predetermined air flow is formed in this way, the ion generator can be It can always function effectively. Also, in general, for ventilation, first-class ventilation in which both supply and exhaust are performed by a machine, second-class ventilation in which supply is performed by a machine and naturally exhausted from the exhaust port, natural supply from the exhaust port and exhaust is performed by a machine There are three types of third-class ventilation performed in, but all use machines. On the other hand, if a plurality of ventilation structures are installed as described above, air supply and exhaust can be performed without using a machine, and energy consumption can be suppressed.
